To the' corners of the. dipper, and thus to attach cornerpieces 2 and 3"-see especially Fig. 3. To one of these, namel 2', we pivot the braces 4, which extend bac` andare atthe endsof the double flanged back 1, We 'l 'tached to the handleA andfto the other we i pivot the nose 5, of the handle, the pivot beinglplaced immediately adjacent to the bottom landrear corners ofthe dipper. By'thisme'ans the points of attachment lof the and handle are placed 'as. far apart as practicable, so thatin lifting a load, the

dipper is subjected to :the least practicable strain. The nose' 5 of the handle. being proper" broughtnearly `,opposite the center of the orso located with reference to the s g bottom 'o gthedipper that it does notinterfere with the koperationfof the'latter..

As it will be understood by reference -to. Fig. 2, the nose 5 is, in fact, intwo parts,` which are bolted` to the o osite--Ifbeams composing the handle .A. eilling piece 9`see Fig. 2-lies 'between and spaces a art the two portions 10-10 comprising the .an-

same boltswhich secure the Shanks or up er portions of the nose-piece 5 passing a so through the filling-piece 9, so that 'all-the parts i i are rigidly connected. Another4 block 12- see Fig'. 3-is. arranged between the outer -ian'ges of the handle bars and to -these the rear ends ofthe bars 4 are attached by means of a bolt 13, which may be adjusted in different holes formed in the vbars wherebg' the angle -of the handle to the clipper may be changed at will,

according to the kind of work 4for which the dipper may b e 1.

employed, that is to say, according to the condition of the earth in which the dip er is being used for excavating. A13, bei locatedon the sides ofthe handle A,'ar`1d t e blocks 12 being secured between the ianges4 thereof, it is apparent that the strongest practical connection is formed, while the Weight is reduced to a minimum.

The formgof the teeth enables support it when the dipper is being lifted, 'While the vextension of t vents injury to,l or rapid Wear of, the latter incase large stones are encountered indigein i g nderneath the bottom 6 of the di per B, and arallel to the arms 7 is arranged) able atch 15fs`ee Figs. 8,-9,-1O`-t he'same lconsisting of a straight bar arranged in keep ers'16, and adapted-to enter a pocket in a `piece, 17, which is pendent fromtheside of the dipper. The latch bar 15 is constructed the saine at each end and provided with a series of holes for attachment of a `,chain or other device for sliding the bar'. The latter,`

is thus adapted to be reversed. asrequired.

The same bolt that-attaches the chain to` the latch also passes through stop plates 19 which are additionally secured bytwo other bolts. 4These platesliinit the movement oi' the latch 15 by contact with the keepers 16,

bui are necessarily ci' suchV length relative to the space between said keepers that they permit the latch to slide far enough to engage with, and disengage from' the socket 17.

The rigid body oi shell oi" the dipper is construeted1 practically of twoparis, nainely, a single sheet of plate metal bent or curved to the roper form, and the I-back which is rivete to and connects the edges-of said shell, the brackets or plates -2-3 beingbolied to,v both the shell and back. The handle, or more specifically, the nose piece directly ai'- tached thereto, is pivoted tov these -brackets or plates instead of being attached to the back ro er, as is the usual construction, so that t e Iback is not weakened by boring for insertion of bolts or rivets'7 and may be rnade comparatively light. Further, the curved the earth and e shanks across 'the body greatly strengthens the latter .and p r'e a slid-l *armsl carrying the swinging bottom or doorf* of' the dipper .are also'attached to the said brackets or plates, 3,.instead of' the back f i proper.

What We claim is: y 1. The improved dipper handle compris,-

ing', as to its body, -tw'o light pieces of iianged iron spaced apart but 4rigidly Asecured together, and a nose-piece ycomprising parts v vhich4 are bent downwardly at `their outer ends, the shaiiks or 'bo-dy portions being arranged betiieen the exterior flanges of the said pieces and securely bolted in place, substa-niially as described.

2. The combination, with a dipper, alian-A dle formed Voi" I pieces,`l iaving anose bent downward, andpivot blocks 12 secured be- -tween the flanges yoi said pieces, oii.l iaces 4 pivoted to 'the upper corners ot the dipper back, and their opposite ends pivoted to said "blocks and liaying'a series of holes providing ior adjustment oi the'pivot bolt, as shovin and described; l j

' 3. The improved dipper body having a back'which is an I-plate, the v[langes of the same being 'riveted to the edges of the body,

-as sho nand described.

, 4. The combination with 'the body of the dipper having brackets 22 and 3 3 'at` tached at its corners, of the bottom arms 7,

handle pieces 5, .and scribed. i I

' 5. The combination vvith the body of the dipper, of a-series of teeth projecting for ward braces 4, pivoted as defrom iis edge,the saine being beveled on the upper andlunderside and made broadest ai. -their outer ends and tapered rearward therefrom, the" 'shanksof the teeth being slotted to embrace the edge ol.' the dipper body, and the upper portion of 'the shank being ext-end ed across the side of the dipper, thus forming ribs on the interior of the dipper, as shown and described. i

y6. The-dipper' provided with projecting ioo bevelediteeih Whose outei ends are broader.

than 'the remaining portion which is tapered backward, as sho n and described.`

7. The combination with the dipper body and the bottom hinged thereto and provided. with keepers, oi a latch held slidably in said keepers and consisting oi" a reversible latch bar vshich is similarly constructed at botli ends and provided witha series of transverse holes, and a kee ei on the body of the dipper which the late shown and described. y
